The second Wire, designated by letter S, fastened at one end to the terminal S, passes through e portion of the slot l, hack through slot 2, thence down througgli the duet S3 which passes underneath the slot 3 thence through the slot 4 and through a, duct formed betweenthe partitions intermediate the slots 4; and 6, back through the chambered portion of the slot 6 and through a duct R, e shown clearly in Fie'. 5, thence up and through a ehemhered portion of the slot 9i through a duct connecting the slots 9 sind l() and through the latter, thence through n duet 7, hach through a, slot i437 'through e duet between the slots 13 and le and heel: to the terminal R8. ln this modified form7 it will be noted that the two wirings are er noeenee ranged in alternate rela?

By this arrangement, either one circuit or the other may he utilized muy be desired, according to the degree' of heat wished to he produced. this arrangement of heat Unite7 it will be noted that the heat will he evenly distributed over the entire Surface of the pleite and the bottoni oi? the latter will he sn'rooth, efcepting et the points where the terminals pass through.
